A coastal flood advisory for moderate flooding runs through 8 p.m. Saturday, Oct. 24. Here are the 2026 king tide dates and the city's advice for drivers.

High tides could put water on low-lying streets and yards in coastal Miami-Dade through Saturday morning. The National Weather Service in Miami issued a coastal flood statement at 1:45 a.m. Friday for “isolated minor coastal flooding.”

The statement covers coastal Miami-Dade County, which includes Coral Gables, along with coastal Broward, coastal Collier, mainland Monroe and far south Miami-Dade. It runs until noon Saturday. The weather service expects “some water on low lying roads and property.” Its instruction is plain: “Do not drive through flooded roadways.”

Updated Oct. 22: The weather service has now issued a coastal flood advisory for moderate flooding in coastal Miami-Dade, in effect until 8 p.m. Saturday, Oct. 24. The Virginia Key gauge reached 1.72 feet Wednesday evening. Read our story on the advisory and the high tide times.

A statement is the weather service’s lowest level of coastal flood alert. It is not an advisory or a warning.

What the tide gauges showed Friday

The water was already up Friday morning, according to the National Water Prediction Service:

  • The Virginia Key gauge read 1.52 feet above mean higher high water, the average of each day’s highest tide, at 9:06 a.m. That is the gauge’s minor flood stage.
  • The Haulover gauge on the Intracoastal Waterway read 1.14 feet at 7:54 a.m., at its action stage, the step below minor flooding.

More king tides are coming

This week falls inside the season’s king tides, the highest tides of the year. The city’s king tides page lists these 2026 periods from NOAA predictions:

Period Moon phase
Sept. 24 to Oct. 15 Full and new moon
Oct. 22 to Nov. 12 Full and new moon
Nov. 22-29 Full moon
Dec. 22-27 Full moon

The city said the effects are felt mostly along the coast and in very low areas near water. It calls this “sunny day flooding”: streets can flood with no rain at all.

The weather service forecast for Coral Gables calls for a chance of showers and thunderstorms Friday and Saturday, with highs of 89 and 90 degrees.

Hurricane Isaias is in the northern Gulf

No watch or warning from Hurricane Isaias covers South Florida. At 7 a.m. CDT Friday, the National Hurricane Center placed it about 245 miles south of Pensacola, Florida. It had sustained winds near 110 mph and was moving north-northeast at 15 mph, about 470 miles from Coral Gables.

The center expects Isaias to become a major hurricane and make landfall on the northern Gulf Coast Friday night or early Saturday. A hurricane warning runs from Ocean Springs, Mississippi, to the Bay-Gulf county line in the Florida Panhandle. Coral Gables is not in any of the storm’s watch or warning areas.

What it means for you

The city’s advice for king tides:

  • Move cars to higher ground before the high tide, and rinse them with fresh water if you drive through salt water.
  • Do not drive through flooded streets. Find another route.
  • Avoid walking through floodwater. If you must, wash your hands, clothes and pets afterward.
  • Boaters: check the tide before leaving the dock. High water lowers the clearance under bridges.
  • If you live in a flood zone, keep sandbags on hand and review your flood insurance.
  • Send photos of tidal flooding on your street to sustainability@coralgables.com. The city uses them to document where water collects.

To check your own street’s flood risk, the city points to the NOAA Sea Level Rise Viewer. Our hurricane prep guide covers evacuation zones, sandbags and supplies for the rest of the season, which runs through Nov. 30. For a non-emergency question, call the city at 305-446-6800.
